Using Auto ISO Makes Exposure Setting Easier
Previously, we discussed the importance of correct Exposure and how the ISO plays a big rule in exposure adjustment. Likewise, Auto Shutter speed or Aperture, most of the new cameras have Auto ISO as well. In this article, I am going to focus on the Auto ISO.
What is Auto ISO?
Auto ISO was introduced into digital cameras several years ago to help photographers maintain the choice of settings to arrive at a correct exposure. Using Auto ISO allows the camera to push the ISO up whenever it calculates the settings and finds out that the shutter speed and or aperture alone cannot create the correct exposure. Therefore, all new Digital cameras (including new DSLRs and mirrorless cameras) have an Auto ISO setting.
When manufacturers introduced Auto ISO, many photographers didn’t like the idea of leaving it to the camera to set the ISO. I would say they were right, only to a degree.
Normally you don’t want to shoot at a high ISO because your photos can get grainy (noisy), but with the new sensors, you can easily shoot images at 1600 ISO or even higher, with no noticeable noise![/vc_column_text][vc_single_image image=”21951″ img_size=”600×600″ add_caption=”yes” alignment=”center” style=”vc_box_rounded” onclick=”link_image” css_animation=”slideInRight” title=”Using Auto ISO”][/vc_column][/vc_row][vc_row][vc_column][vc_custom_heading text=”Benefits of using Auto ISO” font_container=”tag:h2|font_size:35|text_align:left|color:%23aa3300|line_height:1″ use_theme_fonts=”yes” css_animation=”fadeIn”][vc_column_text]The real value of using Auto ISO is, it can, however, in specific situations, help you to shoot sharper and better images faster, with less fiddling around with shutter speed or aperture.
Here are some tips:
Example 1: When shooting a sporting event, and wanting to keep fast shutter speed. However, some of the action happens in the shade and the others in the light. Set your camera to Auto ISO, and it becomes your best assistant in this case. It will change the ISO to maintain the Exposure (shutter speed and aperture combination), regardless of whether your subject is in the shade or the light.[/vc_column_text][vc_single_image image=”15677″ img_size=”600×700″ add_caption=”yes” alignment=”center” style=”vc_box_rounded” onclick=”link_image” css_animation=”slideInRight” title=”Auto ISO”][vc_column_text]
When you shouldn’t use Auto ISO
Using Automatic ISO can make photography easier under difficult light conditions. However, there are times that photographers shouldn’t use it. Here are a few of them:
-Shooting static scenes, such as landscape, macro, or even portraits, since shutter speed is not the main concern. Where you want to control the Depth of Field and Dynamic Range of the photo,
-In Flash Photography, especially if you use off-camera flashes.
These are just a few examples. I will cover more tips in using Automatic ISO soon. So, stay tuned.
-If you are going for a long exposure, Automatic ISO can drive you nuts! Therefore, turn it off for long exposures.
